Researchers from Valencia, London and Sul, Brazil, have performed research to develop adhesive materials that will prevent white stains from appearing on the teeth of people who use brackets.
What if you hardly ever consume soft drinks or eat anything acidic, but still have dental erosion on your teeth? Do genes play a role? And does it matter if you are a boy or a girl?
Do children really need their baby teeth? Many believe that primary teeth aren't all that important. After all, they typically fall out by age 12, and new, adult teeth take their place.
New research by scientists at King's College London has found that tooth loss may contribute to musculoskeletal frailty in the over 50s, with those with fewer than 20 teeth being at greatest risk.
Almost as soon as lasers were invented in the 1960s, curious dentists wondered if these powerful forms of light could be used on teeth, though those early lasers were much too crude for any useful dental work.
Most people regard glass as being chemically stable and inert. This is certainly the case for the type of glass used in windows, which importantly, doesn't dissolve in the rain.
(HealthDay)—Do you feel a sharp pain when you eat or drink something cold or hot? You may have sensitive teeth, a common problem caused by a number of factors.
Seven years ago, Holly and Rob Waldman's second child, John Michael, was diagnosed with autism after an intense day of testing at the Kennedy Krieger Institute, a Johns Hopkins affiliate that specializes in treating neurological ...
Biting and chewing force our buried teeth to emerge, not an innate 'eruptive' force from within the bone of the jaw as previously thought, according to biomechanical modelling done by Babak Sarrafpour and an interdisciplinary ...
Teeth (singular tooth) are small whitish structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, and chew food. Some animals, particularly carnivores, also use teeth for hunting or defense. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of tissues of varying density and hardness.
Teeth are among the most distinctive (and long-lasting) features of mammal species. Paleontologists use teeth to identify fossil species and determine their relationships. The shape of the animal's teeth are related to its diet. For example, plant matter is hard to digest, so herbivores have many molars for chewing. Carnivores, on the other hand, need canines to kill prey and to tear meat.
Mammals are diphyodont, meaning that they develop two sets of teeth. In humans, the first set (the "baby," "milk," "primary" or "deciduous" set) normally starts to appear at about six months of age, although some babies are born with one or more visible teeth, known as neonatal teeth. Normal tooth eruption at about six months is known as teething and can be painful.
Some animals develop only one set of teeth (monophyodont) while others develop many sets (polyphyodont). Sharks, for example, grow a new set of teeth every two weeks to replace worn teeth. Rodent incisors grow and wear away continually through gnawing, maintaining relatively constant length. Many rodents such as voles (but not mice) and guinea pigs, as well as rabbits, have continuously growing molars in addition to incisors.
